#### Performance data:
Measurement of exercise metabolism consists of collecting during physical activities (e.g. running, cycling, rowing, etc.) a number of physiological variables (including breathing flow, exhaled CO2 fraction, heart rate) and environmental signals (ambient temperature, pressure and humidity) in order to calculate the following main parameters:
- VO2 (ml/min) Oxygen Uptake, known also as Oxygen Consumption ●
- . VCO2 (ml/min) Carbon Dioxide production
- VE (I/min) Minute Ventilation
- HR (1/min) Heart Rate ●
- . RQ (---) Respiratory Quotient
Measurement of resting metabolism consists of measuring at rest the following main parameters:
- VO2 (ml/min) Oxygen Uptake, known also as Oxygen Consumption ●
- VCO2 (ml/min) Carbon Dioxide production .
- RQ (---) Respiratory Quotient ●
- EE (Kcal/day) Energy Expenditure ●

#### Non-clinical testing:
Subject device non-clinical testing confirms that the device meets its specification, including the requirements of relevant standards:
- Electrical safety in accordance with IEC 60601-1:2005
- EMC in accordance with IEC 60601-1-2:2007
- Accuracy validation (Vt, RF, VO2, VCO2) .
- . Coexistence testing (FCC Part 15)
- Protection provided by enclosure (IEC 60529:2013) ●
In relation to biocompatibility, all of the K5 components that are either intended to contact the patient or may come into contact with the patient during use have been previously assessed for their biocompatibility, as appropriate for the nature of their body contact and contact duration, by FDA within already-cleared 510(k) submissions.
The results of the above testing, together with previous FDA clearances, assist in the demonstration of substantial equivalence of the subject device with the predicate device.
